MTM
Message Buffer Transmission Mode — This control bit applies only to transmit message buffers and defines
the transmission mode.
0 Event transmission mode
1 State transmission mode
14–13
CHA
CHB
Channel Assignment — These control bits define the channel assignment and control the receive and transmit
behavior of the message buffer according to Table 3-77.
12
CCFE
Cycle Counter Filtering Enable — This control bit is used to enable and disable the cycle counter filtering.
0 Cycle counter filtering disabled
1 Cycle counter filtering enabled
11–6
CCFMSK
Cycle Counter Filtering Mask — This field defines the filter mask for the cycle counter filtering.
5–0
CCFVAL
Cycle Counter Filtering Value — This field defines the filter value for the cycle counter filtering.
